Not too much.  Especially as I'm not sure what you are actually
running.  If I run the workloads/randomrw.f from the filebench git
repository, it fails to run due to a lack of a run statement, and it
also hardcodes /tmp.  Can you share the actual randomrw.f used for the
test?

Also do you run this test on other local file systems exported by
NFS, e.g. XFS and do you have numbers for that?
